A sleeping black hole has come alive - by @bigbear

in #astronomy4 years ago (edited)

It is eating stars passing it and it is very big. There are many black holes in the solar system some very big others are smaller.

They have found that when a star passes too near a black hole it is immediately eaten by the black hole.

There are so many black holes, and we do not really know what the reason is and we have learnt that they can really do some damage to starts.

The feeding process makes a lot of energy and x rays when it does devour the star.

" Pasham said. "The debate has been, where are these really energetic electrons coming from?"

They think that when a black hole devours a star the energy shock make radio waves that make the energy.

These radio waves would look dramatically different from the pattern of X-rays created by the infalling stellar material. But the signal Pasham and Van Velzen found in the radio is a 90-percent match with the X-ray signal.

They think that the sources from the waves and x rays are linked and helping each other on.

"It's not a coincidence that this is happening," Pasham said. "Clearly there's a causal connection between this small region producing X-rays and this big region producing radio waves."

The new observations, which were published March 19 in The Astrophysical Journal, may help scientists better characterize the physics of jet behaviour. This, in turn, may help improve researchers' understanding of how galaxies evolve.

The rate at which the black hole is feeding is linked to the rate of the energy it is producing and that is why some are small and some are so big.

Interesting information on something I know very little about.
